when I pulled my motor I pulled the motor and tranny separately.
Anyway, I used 4 ratcheting tie down straps attached to a harbor freight engine load leveler.
essentially I put an old towel on to of the valve cover, set the leveler on it, then attached
a strap to a chain, around the motor and then to the other side chain.
I put 2 straps on the front and 2 on the rear. Ratcheted them down fairly snug.
There may be a way to use the head bolts as a connecting point but I am not sure
